OBJECTIVE: To investigate Enterobius vermicularis infection among primary school students and its influence factors in Chongqing.
METHODS: Beibei and Changshou were selected as investigated points from October to December 2011. One primary school was randomly chosen from each of the 5 different directions in every investigated point. Adhesive cellophane anal swab was used to examine pinworm eggs for 3 consecutive days. Information on children's family, hygiene habits and school environment was collected by questionnaire.
RESULTS: The total infection rate of E. vermicularis was 6.7% (71/1 071). The infection rate in rural schools (7.9%, 60/755) was higher than that of urban schools (3.8%, 12/316) (chi2 = 6.1169, P < 0.05). The rate in males and females was 6.3% (34/536) and 7.1% (38/535), respectively (chi2 = 0.2463, P > 0.05). Among the investigated children aged 6-12 years, the infection rate in 6-year-old children (16.03%) was highest. There was a statistical significance among age groups (chi2 = 29.1492, P < 0.01). With the increase of age, the rate decreased. Multivariate logistic regression analysis showed that location (OR = 0.411), age groups (OR = 0.714), education level of mothers (OR = 0.568), materials of classroom-ground (OR = 0.116) and types of boarding (OR = 0.272) were the influence factors on E. vermicularis infection in primary schools (P < 0.05).
CONCLUSIONS: Pinworm control should more focused on rural children, younger group, mothers with lower education, classroom with cement ground and lodging schools in Chongqing City.
